Understand 3D glasses

There are three different types of 3D glasses—active, passive, and 3D Dual Play—and the type of glasses you use for your TV depends on what type of 3D your TV displays.

Active (shutter)

Active-shutter glasses work by communicating wirelessly to your TV through a built-in emitter. Each lens is essentially a mini LCD screen that actively lightens and darkens with the 3D content. LG active-shutter glasses use rechargeable batteries that you can charge by simply plugging them into the USB port on your TV.

Purchase active-shutter glasses
You can purchase active-shutter glasses from a number of electronics retailers. Just be sure to get the correct glasses based on the model release date of your TV.

Passive (polarized)

Passive glasses are polarized and are designed to block different amounts of light to each eye to create the illusion of depth. Because of the simplicity of the lenses, these 3D glasses don't require batteries or recharging, and are often much less expensive than active-shutter glasses. LG Cinema 3D passive glasses are also available in clip-on format (sold separately), allowing anyone wearing corrective lenses to enjoy 3D entertainment without having to wear two pairs of glasses.

3D DUAL PLAY GLASSES

3D Dual Play glasses are made for two-player split-screen gaming. While wearing the lightweight battery-free glasses, each player can see only their character's point of view (in 2D) across the entire screen. Which means no more squinting at a smaller split-screen view and no more cheating by peeking at your opponent's screen.

Dual Play works with most current gaming systems, and even works with most split-screen games on older consoles. Dual Play glasses are compatible with the 2012 LM and CM series TVs.

For a small percentage of the population, the viewing of stereoscopic 3D video technology may cause discomfort such as headaches, dizziness or nausea. If you experience any symptoms, discontinue using the 3D functionality and contact your health care provider.
